  • Multi-sectional utility pole having slip-joint conical connections
    Patent number: 6399881
    Abstract: A multi-sectional utility pole includes at least two sections of straight pipe, which are joined and connected by a slip joint connection. The slip joint consists of two mating conical sections, with one attached to each section of the pole. The slip joint is compressed with the aid of rings, which are attached to the pipe, and a key and slot. The conical sections can be swaged from the ends of the pipe, or can be fabricated separately and welded on to the ends of the pipe.

    Publication number: 20010013419
    Abstract: A multi-sectional utility pole includes at least two sections of straight pipe, which are joined and connected by a slip joint connection. The slip joint preferably consists of two mating conical sections, with one attached to each section of the pole. The slip joint is compressed with the aid of rings, which are attached to the pipe, and a key and slot. The two conical sections are fastened together with bolts that pass through the female conical section and thread into the male conical section of the slip joint. The pole is easily assembled on the ground and the pole sections are fungible with other sections of the same diameter. The sections are also inexpensively manufactured. The conical sections can be swaged from the ends of the pipe, or can be fabricated separately and welded on to the ends of the pipe.
